Applying nitrogen (N) fertilizer at irrational rates and basal topdressing ratios typically leads to high resource wastage serious environmental pollution is a global problem. A pot experiment was conducted between 2020 2021 investigate the effects of different N application on growth, yield, quality, water- N- use efficiencies forage maize. Four treatments were used, with following levels: 0 k...
Soil water, salinity and nitrogen content are three major factors affecting crop production in arid and semi-arid areas. This study was performed in two years of 2009 and 2010 in a semi-arid area in order to investigate the effects of irrigation water quantity (as main plot), quality (saline water, as sub-plot), nitrogen fertilizer (as sub-sub plot) and their interactions on growth and yiel...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
In the present study, some nutritional imbalances, specific ion toxicity and yield-ion concentration relationships in maize under water, nitrogen (N) and salinity stresses were assessed. Effect of different levels of irrigation water (I1=1.0ETc+0.25ETc as leaching, I2 =0.75I1 and I3 =0.5I1) as main plot, salinity of irrigation water (S1=0.6, S2= 2.0 and S3=4.0 dS m-1) as sub-plot and N fertiliz...
Water and fertilizer applications management should be improved due to scarce resources and environmental protection aspects. An analysis of crop yield production and profit maximization was conducted to determine the optimal water and nitrogen allocation. In this study, maize grain yields were predicted for 25 different amounts of irrigation water (350-1700 mm) and 46 different rates of nitrog...

to study yield and its relationships with yield components in 10 varieties of foxtail millet (kfm1 to kfm10), an experiment was carried out in safiabad agricultural research center in rcbd design with three replications for a period of three years (2003 to 2005). vegetative and reproductive characteristics of each cultivar were recordered during the growing seasons. three year results showed si...
Research focusing on the nitrogen (N) application and N use of forage maize (Zea mays L.) in boreal region is either limited or non-existent. The aim this study was to investigate response yield, quality recovery efficiency (NRE) an increase rate different climatic conditions two locations Finland. field experiment conducted southern (Helsinki; 60° N) central (Maaninka; 63° Finland 2019 2020. D...
Effects of different levels of nitrogen fertilizer and cutting time of forage on grain and forage yield of barley (Hordeum vulgare L.) Karoon cultivar was studied during 1995-1996 at Ramin Agricultural Research and Educational Center, University of Shahid Chamran, Ahwas, by using a split plot design in randomized complete block with 4 replications. Main plots were assigned to five levels of N f...
In order to study the effects of weeding and plant density on forage yield of two sorghum cultivars, an experiment was conducted in 2011 at Bahonar University of Kerman Research field station. The experiment was designed as a randomized complete block with a factorial-split treatment arrangement and with three replications. Treatments were included four levels of weeding (whole season wedding, ...
